BERLIN (Reuters) - Huawei Technologies showcased its chipset for a new high-end smartphone on Friday, pressing ahead with plans to launch its Mate 30 range, despite uncertainty about whether the new phones will be able to run Google’s Android operating system and apps.

The Chinese tech giant bills the Kirin 990 chipset as the first all-in-one 5G system on a chip, describing it as superior to alternatives from Qualcomm (QCOM.O) and Samsung (005930.KS) that, it says, graft 5G modems on to 4G chips.

“It’s the world’s most powerful 5G system on a chip. It’s the world’s most powerful 5G modem,” Richard Yu, the head of Huawei’s consumer business group, said in a speech in Berlin.

Huawei’s launch at the IFA consumer electronics fair in Berlin of the Kirin 990, made using the latest 7 nanometer production process, is part of a carefully sequenced buildup to the Sept. 19 international launch of the Mate 30 in Munich.

Yet, say Huawei sources, it is still not known whether the Mate 30 will be able to run services from Alphabet’s Google (GOOGL.O) following the blacklisting of the Chinese company by the U.S. administration in May.

The world’s No.2 smartphone maker is looking to reclaim ground as the spread of ultra-fast 5G networks prompts an upgrade cycle among consumers who have been holding on to phones for longer. Consumers will need new handsets to take advantage of the ultrafast download speeds promised by 5G.

NO GOOGLE, NO JOY

The services in doubt include pre-installing the Google Play store and a suite of popular apps such as Google Maps that buyers would expect to be available from the moment they turn on their new phone and synch it with their profile.

Huawei’s fallback option would be to run the devices on its home-grown Harmony operating system, although company officials and analysts say it is not yet ready for prime time.

“The elephant in the room is Google,” said Peter Richardson of Counterpoint Research, after attending a technical briefing on the Kirin 990 by Huawei managers that skirted the issue and focused only on the chipset’s specifications.

The Kirin 990 packs more than 10 billion transistors and can support downlink speeds of up to 2.3 gigabits per second.

It has an adaptive receiver that enables it to switch between 4G and 5G where coverage of the faster technology is weak.

And, to save energy, it has a ‘big core’ to handle powerful computing tasks with the support of artificial intelligence, and a ‘tiny core’ for less demanding operation.

Huawei plans only to use the Kirin 990 in its own devices, meaning it lacks the marketing opportunities enjoyed by Qualcomm, whose chips already power the Samsung 5G phones, such as the Galaxy 10, already on the market.

Apple’s recent settlement of a patent dispute with Qualcomm, and Intel’s (INTC.O) exit from the smartphone modem business also reflect the U.S. chipmaker’s muscle in a global market that is increasingly fragmenting due to the U.S.-China trade tension.

“Qualcomm has a scale advantage,” said Ben Wood, analyst at CCS Insight. “Huawei’s commitment to continue innovating on silicon is really impressive, especially given the geopolitical headwinds they are facing.

“But at the end of the day, it’s a single-vendor solution. And, even if they had aspirations to sell the chipset, that is getting more difficult all the time.”
